| Class | Description |
|---|---|
| CancelJobSupervisorOperation |
This operation is fired by the jobs owner node to remotely cancel the defined jobId on all nodes.
|
| FireNotificationOperation |
This operation is used to transport and execute a notification on a remote node since
the current event service is not capable of reliable transmission so this is a fallback
to sync operations which is hopefully only a temporary workaround!
|
| GetResultOperation |
This operation is used to retrieve results from a remote node
|
| GetResultOperationFactory |
This class is used to create
GetResultOperation instances. |
| KeysAssignmentOperation |
This operation is used to request assignment for keys on the job owners node.
|
| KeysAssignmentResult |
This class is used to store assignment results in
KeysAssignmentOperation
executions. |
| KeyValueJobOperation<K,V> |
This operation is used to prepare a
KeyValueSource based
map reduce operation on all cluster members. |
| NotifyRemoteExceptionOperation |
This operation is used to inform the job owner of a remote exception
|
| PostPonePartitionProcessing |
This operation is used to tell the job owner to postpone a mapping phase for the defined
partitionId.
|
| ProcessingOperation |
This is the base class for all map reduce framework operations, it always contains the name of
the JobTracker and the unique jobId
|
| ProcessStatsUpdateOperation |
This operation is used to update the process statistics on the owner node
|
| RequestMemberIdAssignment |
This operation is used to do some kind of partitionId based processing on non partition based implementations
of
KeyValueSource (not implementing PartitionIdAware)
which can happen for custom data sources like distributed filesystems that are up to the end user on how to
manage the distribution. |
| RequestPartitionMapping |
This operation requests a new partition to process by the requester on the job owning node
|
| RequestPartitionProcessed |
This operation tells the job owner to mark a partition as fully processed
|
| RequestPartitionReducing |
This operation tells the job owner to start reducing phase of the defined partition on the first
occurrence of a full emitted chunk
|
| RequestPartitionResult |
This class is used to store the requested result of all kinds of processing operations.
By default it holds a basic result state and maybe the partitionId it was operated otherwise it's value is defined as -1 |
| StartProcessingJobOperation<K> |
This operation is used to start the actual processing after all node prepared to execute the map reduce job
|
| Enum | Description |
|---|---|
| RequestPartitionResult.ResultState |
This enum is used to define the basic state of an operations result
